Java Java Basics Using your New Tools Multiple Strings

Why not just use console.printf(variableName + " rest of sentence.");

Why not just use that instead of ("%s rest of sentence.", variableName); Wouldn't you end up typing all the variable names AND typing a bunch of %s. Couldn't you save a lot of time just typing in the variable name where they're supposed to be?

I did it on the first workspace and it worked.

Hi John,

Yes, you can concatenate strings using the + operator. I think it is considered best practice to use the formatter and placeholders, such as %s, though. There are many types of placeholder, not just strings. I'm not sure if all of those different data types can be added to a string for output.

Have a look at this to see the different numeric placeholder types that are available. Also, read the Creating Format Strings section of this which may help too.
